Q&A with Greg: Black Holes, Consciousness, Greg’s Research, and More!

In this episode of What the Physics?! we answer questions from our viewers. This session tackles questions like:

1. What happens when two black holes collide?
2. Why do certain particles only become detectable at the high energies inside particle colliders?
3. What’s it like to do research in theoretical physics?

If you have questions you’d like answered, comment below or tweet @WTPhysics.

Greg Kestin holds a faculty position at Harvard University, where he conducts theoretical physics research, teaches, and produces educational online content. He earned his physics Ph.D. from Harvard, as a member of The Center for the Fundamental Laws of Nature, focusing on theoretical particle physics and quantum field theory. Over his career, he has also conducted research in nuclear physics, fusion energy, and gravitational wave physics. For over a decade he has been involved with innovative educational outreach endeavors, bringing science to both students and members of the public through his writings, videos, lectures, and multimedia.

This week, NASA announced that it will partner with the European Space Agency to send a 4,760-pound spacecraft into space to peer out over billions of galaxies in an effort to map and measure the universe. Its purpose: to investigate the mysteries of dark matter and dark energy.
